You are right, I will skip option 1). Just checked the transfer LHR/LGW and it looks like that I would have to book a business class ticket for CHF 4350 and then pay for the bus to Gatwick. Well, thats shabby.
Just checked another very wild routing, which gives a long travel time and two stops and is not what I like, but shows that you may reach any point on earth via any direction: Air Berlin ZRH TXL MIA (AA) MCO but only CHF 2285 return..

Interesting, will check that one as well, perhaps a little longer travel time, may be?
